We do PPC but no classified ads. There are all the usual sources of traffic in the analytics except this one. The website is an auction website so I am wondering if it is something to do with if you are registered as a individual member or a company and it is when you return to the website and are automatically logged in or something. We have a few other auction websites and they show the same thing in Google Analytics. All of the other sites that we have do not have anything like this.
I contacted Google and they gave said that it was tagged classified listings that we have running but we do not have any. Seems a bit strange that it is only on auction websites and no other sites.
